Ivy
Medicinal Uses,
Interactions, Side Effects
Common or English ivy is an
evergreen climbing vine; it differs from ground ivy (Glechoma
hederacea) and from American ivy (Parthenocissus quinquefolia)
and the related Virginian creeper. Ivy is grown widely, but the
commercial product is obtained mainly from Eastern Europe. The
leaf is the part that is applied medicinally.
Uses:
The European indications that are
currently in favor are primarily for the respiratory tract. In
Germany, ivy is recommended for its expectorant effect in dry
cough, common cold, and chronic respiratory tract disorders.
Extracts have been used as antispasmodics and as topical
treatments of dermal infections and itching, as well as for
weight loss. Common ivy also has been traditionally used for
arthritis, scrofula, fevers, skin parasites, burns, and
infections.
Pharmacology
The main components of interest
are saponins (3-6% content, including hederin and
hederacosides), flavonol glycosides (including rutin and
kaempferol), sterols (including stigmasterol and sitosterol),
sesquiterpenes, and polyalkanes (including falcarinol). The
constituents in ivy are considered to have a mucokinetic
effect, and they are reported to help loosen abnormal mucus in
the respiratory tree. There is some evidence from animal
experiments that ivy's saponins can increase respiratory tract
secretions and can prevent acetylcholine-induced bronchospasm
in guinea pigs. A product containing its chief constituent,
hederasaponin C (hederacoside C), has been shown to have
antifungal properties and to be toxic to some parasites and
bacteria.
Clinical
Trials:
Several controlled clinical
trials have been carried out in Germany with Prospan, an ivy
extract produc. In one double-blind, randomized,
placebo-controlled trial of short duration in 24 children with
asthma, findings suggested a bronchospasmoly tic effect as
shown by statistically significant and clinically relevant
improvement in airway resistance and intrathoracic gas volume.
A few other double-blind controlled studies on patients (hronic
obstructive pulmonary disease suggest that ivy has , and
physiologic value. The largest of these involved qiven ivy
extract or an established mucusloosening drug,oxol; the
benefits after 4 weeks of therapy were similar. the study
lacked a placebo control, and since it is . to demonstrate the
value of any mucokinetic agent, the , effectiveness of ivy
remains uncertain.
Adverse
Effects:
There are no known side effects
of common ivy products.
Inleractions:
No drug interactions are
recognized.
Cautions:
There are no data on ivy leaf in
pregnant or breastfeeding women. Falcarinol, which is found
mainly in the leaves, can cause contact dermatitis. Oral
ingestion of the bitter ivy berries can be toxic.
Preparations &
Doses:
In Europe, preparations are
available as teas, skin products, cosmetics, shampoos,
anticellulite creams,and in proprietary mixtures such as those
used for bronchitis. The typical daily dose is 0.3 g of crude
herb or equivalent extract for bronchitis.
Summary
Evaluation
Products containing ivy leaf are
among the many herbal remedies may appeal to patients with
coughs, sinus problems and bronchiitits. Several controlled
clinical trials in Germany showed possible benefits, but the
value of these or any mucus-loosening ajents are difficult to
prove.
